Justin Bieber, who wasn’t even at the show, also got caught in the wrath of Armstrong. “I’m not f—ing Justin Bieber, you mother—-ers. You’ve got to be f—ing joking. I got one minute. One minute left. Now I got nothing left.”

And as he threw his microphone down, the lead singer started to trash his expensive looking guitar and stuck the middle finger out to the crowd.

Yikes! I can see how Armstrong may have overreacted. But to be fair, it wasn’t very considerate for the other artists to take over another musician’s set time.
